Title

Heating Water and Seawater with Sunlight

Problem Scenario

In my experiment i want to figure out what type of water would heat up the fastest using the sun or heat lamp substitute. I believe that if i crossed the thermometers and put them in the wrong water i would have to redo my whole experiment. I also believe that i could put the wrong amount of water in each glass making me have to redo my project. Another thing i believe is that the water could not be heated right if the heat lamp substitute is placed the wrong way.

Broad Question

Would the rising of the temperature of the water and saltwater differ with more, less, or no salt at all?

Specific Question

While adding more salt to the water will the temperature or the water increase slower or would the temperature rise pretty fast, increasing faster then the regular water?

Hypothesis

I think the regular water will warm up faster because the salt in the saltwater will slow down the increase of temperature.

Variables

Independent Variable: Time

Dependent Variable: Temperature

Variables That Need To Be Controlled: Time, Sun, Water, Salt

Vocabulary List That Needs Explanation

General Plan

1. Get four clear glasses to put the water in them
2. Get heat lamps to heat the water.
3. Put water and thermometers in the glasses and add certain amounts of salt in the glasses.
4. Put the glasses and thermometers under heat lamp.
5. Put the glasses and the thermometers in the heat lamp light and retrieve my data.
6. Get my data from the observation and do the experiment 2-3 more times.
7. when i get all my data i will graph it and write a reflection.
8. put all my data and everything i got from the experiment and make my poster.
9. finish poster and get my whole experiment to bring to science fair.
10. READY FOR SCIENCE FAIR!

Potential Problems And Solutions

it may be to cold for the glasses so it would be hard for the water to warm up. I can fix this problem by putting the water inside and use a heat lamp.

Safety Or Environmental Concerns

Will the lamp be a good sun substitute?

Experimental Design

(add the correct headings from the experimental design page before beginning)

What is your experimental unit?

This is the base unit of your experiment, for example, one plant, one ice cube, one dish. It is the thing you will be measuring.
four glasses, four 3/4 cups of water, Salt, heat lamp light.

Number Of Subjects In Each trial:

This is the number of different treatments you will use. For example, if you are comparing rust formation using salt and no salt, there would be 2 subjects in each trial. If you were comparing rust formation with no salt and three different amounts of salt, then you would have 4 subjects in each trial.
four subjects in each trial.

Number of Observations:

How many measurements will you take for each experimental unit times the number or trials
how many times you will repeat the experiment.
3-4 times

When data will be collected

Looking for an actual date or dates here. This is requiring you to commit to your project.
Hope to start Wednesday or Tuesday

Where will data be collected?:

Be specific.
In a note book to keep or on the computer.

Resources and Budget Table

Item	Number needed	Where I will get this	Cost
Glasses	4 glasses	home	0$
box	1 box	store	5-10$
Salt	1 bag	home	0$
thermometer	4 thermometers	store	5$
lamps	2	r biche	0$

Detailed Procedure

1. get clear glasses from home and put 3/4 of the glasses filled with water.
2. i will put regular water in one glass, the amount of salt in the ocean that would fit 3/4 of a cup, one glass will have more salt then the ocean glass and another will have less salt then the glass with ocean water.
3. put the glasses of water and salt water under 2 large heat lamps.
4. put the the thermometers in the water and record data .
5. when gotten the data i will record it and start making my poster and get ready for science fair.
6. i will take my experiment and bring it to school with my poster and then i'm ready for the science fair.

Results

In my Science Fair Experiment i graphed which type of water heats up faster by the sun (or heating lap substitute.). I used regular water, sea water, doubled sea water, and half of sea water. I wanted to find out which type of water heats up faster using a type of light.I found out that the more salt you have, the faster the water will rise. In my experiment i found out that the doubled sea waters temperature heats up faster then any other water i tested. So the results for my experiment are that the doubled sea water heated up the fastest, the regular sea water heated up second fastest, half of sea water heated up third fastest, and the regular water heated up the slowest.

Conclusion

My hypothesis was, the regular water would heat up faster then any other water type. I reject my hypothesis because it turns out that the doubled sea water heats up the fastest. My hypothesis was totally wrong. I thought the regular water would heat up the fastest but it was the slowest. So from the data i received i now know that my hypothesis was wrong and I reject it.

Discussion

My science fair experiment was to figure out what type of water would heat up faster using sun light or heat lamp substitute. I used a bucket to hold four 600ml glasses filled with the different types of water i have made(regular water, sea water, doubled sea water, and half seawater). For heating the water i used heat lamp substitute for the sun due to weather issues To record data i used a lab quest connected to four thermometers to graph and record data. It took me three days to get three different trials of data.

Benefit to Community and/or Science

This experiment benefits Science because if anyone wants to do a project or experiment about water or water temperature, that person could look at this wiki and see which type of water would benefit that persons project or experiment in anyway possible(anyway that can help.).

Abstract

My Experiment was to figure out which type of water would heat up the fastest using sunlight or heat lamp substitute. During the experiment i had to put four 600ml glasses filled with 400ml of water and the different amounts of salt given to each specific glass. I used a Lab Quest connected to four thermometers to record the data. After getting the data for one trial i repeated the experiment two more times. After I have all the data I upload the data onto a computer, to logger lite 1.4. This application allows me to upload my data and it makes a graph automatically. After I have all my data I now can see if i have to reject my hypothesis or not. When all my data is on the computer and on my wiki i now print all things needed on my poster and then I can finish the project.
